Sadolin Superdec Problems
Sadolin Superdec is a popular paint often hailed for its impressive and dependable finish. However, some users have reported encountering issues, particularly when applying the paint on existing gloss. This article aims to shed light on these problems and suggests possible remedies.
The Problem: A concerning issue shared by users is that a few days after applying Sadolin Superdec, the painted surface develops significant blisters. When these blisters are inspected, it’s revealed that the blistering goes right back to the wood. This indicates that while the Superdec paint bonds well with the existing paint, it somehow causes the older layer to blister. The problem seems to exacerbate under direct sunlight.
Possible Causes and Solutions:
- Existing Paint’s Bond with the Timber: It’s suggested that the previous paint might not have been properly bonded to the timber. The remedy proposed is to prime the bare wood before painting. Once the wood has been primed, the affected areas can be filled and blended back in.
- Presence of Trapped Moisture: There’s a theory that the wood’s moisture might be causing the problem. While the wood’s surface might feel dry, the moisture content within could still be high. It’s advisable to use a Moisture Meter to check the moisture content of the wood before painting. Though some believe these meters can give varying readings based on pressure, others swear by their accuracy.
- Impact of the Color Black: Black paint, given its nature, attracts more heat. This means that areas painted black, especially surfaces like window sills, tend to blister more quickly. When exposed to direct sunlight, the paint can become extremely hot, causing it to react adversely. In such cases, it might be worth considering using a different shade or switching to a different brand of paint that’s less sensitive to sunlight.
- Incompatibility with Undercoats: There have been instances where Superdec caused blistering on surfaces previously treated with certain undercoats. If this is suspected to be the cause, it’s suggested to strip back the paint, prime the surface with a different undercoat, and repaint with Superdec.
- External Validation: Sometimes, it’s the paint mix itself. If the issue persists even after following the advised steps, it might be helpful to contact the store or the manufacturer for further assistance.
In conclusion, while Sadolin Superdec is a trusted brand for many, it’s evident that there can be occasional issues. Ensuring the surface is adequately prepped, checking for moisture content, and considering the color and undercoat compatibility can help in achieving the desired finish without complications. If issues persist, always consult with a professional or seek advice directly from the manufacturer.
